Re: Which players have the highest 'TENNIS' IQ?
I voted for Justine. This may surprise no one, but going by the criteria, and really as a general response, I think Justine Henin has shown incredible on-court insight throughout her career as she made tweaks to her game pretty much at every stage of her career. Her game plan is almost always geared to her opponents. Look at how she returns against Lindsay Davenport - using angles and short balls in addition to aggressive winners-mongering - and how she returns against Serena - deep to Serena's body to rob her of time to react in addition to aggressive winners-mongering. I think there are very few players out there who is comparable to Justine when it comes to balance across her variety of groundstrokes - I find that her slices, spins, feel, touch and power all operate at very high levels. There is not one stroke there that you would say is truly weaker than the others.
